SHUTTLE-BO X-OPERATING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 440,487, dated November 11, 1890.

Application filed March 28, 1890 Serial No.- 345,661. (No model.)

following is a specification.

This invention relates to multiplier mechanisms for looms and is adapted to be employed in connection with a pattern-chain.

In carrying out my invention I employ, in

connection therewith, a drop-shuttle-box mechanism operated by vibrating levers con trolled by a pattern-chain through intermediate gear of well-known form and arrangement. (See, for example, patent to Knowles, N 0. 221,237.) My reference to such wellknown mechanism will therefore be brief, as it is herein shown only for the purpose of making clear the structure, arrangement, and operation of the multiplier mechanism.

In the accompanying drawings, Figure 1 represents a portion of a loom in end elevation having my invention applied thereto. Fig. 2 represents an enlarged view of the parts embodying my invention, as shown in Fig. 1. Fig. 3 is a section taken on the line a; as of Fig. 2, the vibrator-levers being omitted, and certain parts being shown in elevation. Fig. 4 is a View in detail of a chain-wheel and portion of chain thereon. Fig. 5 is a view in detail of the multiplier-eontrolling mechanism. Fig. 6 is a view in detail of the compound lever. Fig. 7 is a View in detail of a stop em ployed in connection with the controlling mechanism. Fig. 8 shows a modified form of certain parts.

A represents the frame of the loom; a, the reciprocating support for the dropboxcs; a, the lay; B, the flexible connection between the drop-box support and thecompound lever; b b, the compound lever; C, the vibrator'lelers; c, the connectingarms between the crank-gears on the vibratonlevers and the compound lever; D, the chain -supporting wheels; (Z, the chain-actuating spur-wheel; d, a drive-wheel secured on the main shaft E; e, an intermediate gear-wheel, meshing with the drive-wheel cl and having a pinion e and a mutilated gear E secured to rotate therewith, the pinion e meshing with the chain-actuating wheel (Z and having a cam e for actuating the dog 6 for engaging and releasing the vibrator-levers; F, a mutilated gear-Wheel driven from the main shaft by means of an intermediate gear-wheel f, intermeshing with the drive-wheel (l' and with a wheel F, fixed on a shaft to rotate with the wheel F; and f one of a set of mutilated gearwheels mounted on the vibrator-lever a'ndhaving attached eccentrically thereto one end of the connecting-arm c for operating its section of the compound lever.

The parts to which I have thus briefly alluded are well known in the art, combined and arranged substantially as shown, and it is not thought necessary to give a detailed.

statement of their operation, as the same is well known to those skilled in the art, my present invention pertaining to certain means for controlling the operation of certain of the above-named parts, in order to multiply the effect of a set of rollers on the pattern chain, thereby saving length of chain.

G represents a stud or axle secured in the loom-frame, and provided with a sleeve G, to which the sprocket-wheels D, which support the pattern-chain, are secured, and on which the chain-actuating spur-wheel (Z is loosely mounted. One side of the wheel d is provided with an annular series of pockets 11 ,10- cated at equal distances apart to receive the head of a spring-actuated key, as will appear farther on. A wheel or plate H is lined to the sleeve g inproximity to the wheel (1, and carries a socket 72, projecting from its side, in which a key h here shown in the form of a plunger, is seated, in such a position as to admit of its head 71. entering one of the pockets d as the wheel (Z is rotated on the sleeve. The key h is held normally under springtension by means of a spring 7L3, tending to force it into engagement with the Wheel cl. For the purpose of looking it in released adjustment, I provide its outer end with aha'ndle 7L, having set in its end dowel-pins h, adapted to enter sockets 7t in the end of the wall of the socket h, By simply drawing the key back from the wheel cl until the pins 71, are released from their sockets, and then giving it a partial turn, it may be held in re leased adjustment until again set in position.

The wheel H is also provided with a handle I for convenience in rotating it, and with ratchet-notches 01 on its periphery, the purpose of which will hereinafter appear.

A controlling wheel or plate K of peculiar form is fixed on the stud G in front of the wheel H, and is provided with an annular series of inclined faced ledges 70 along the edge of its periphery, the said ledges being separated by intervening plain spaces 70', a portion of the periphery of the wheel being preferably cut away at such intervening spaces to prevent unnecessary friction between the stud L, to be hereinafter described, and the face of the wheel while the keyis engaged in a pocket in the wheel cl. The opposite side of the periphery of the said wheel is provided with a series of notches k at points opposite the ledges k.

The-handle 71 of the key h has a lateral extension 171 through which a screw-stud L projects into position to engage the ledges 7c as the said key and stud are carried around by the wheel H in engagement with the actua'ting-wheel d. There is also secured to the handle it a stop Z, the free end of which is so located that it will be drawn gradually into the recess k as the stud L rides up the inclined face of the ledge 7t, and just as the said stud passes over the abrupt end of the ledge the end of the stop will engage the wall of the recess k and so prevent the wheel H from further movement in the same direction. The pattern-chain herein shown consists of sections formed by corresponding side links W united with a succeeding pair of side links by pivotal bars 10, on which rollers are mounted and spaced apart in groups of the desired number by sleeves 10 The operation of the parts as thus far described is as follows: Suppose the wheel II to "have been turned bythe, operator to set the pattern-chain in the desired adjustment, and

"the key h to bein engagement withthe actuating-wheel d. As the stud L reaches one of the ledges 7c and travels along up its-inclined face, it will gradually withdraw the key from engagement with the wheel d, and hence stop "thepattern-chain at or near a predetermined point to introduce the desired shuttle. The release ofthe key from the actuating-wheel (l takes place, however, before the stud L "clears the ledge, and in order to advance the wheel H to a position where the stud L will clear the ledge and drop back into position to allow the key to again engage a pocket in the actuating-wheel d, and to bring the patternchain into proper-adjustment, I provide a push-pawl in engagement with the periphery of the wheel H. One form of such push-pawl is represented at M, the same being mounted on an eccentric m on the main shaft, with its free end resting in contact with the wheel H in position'to engage one of the teeth 2' at the proper time to complete the rotary movement of the wheel for the above said purposes. When such movement of the wheel H is comthe key 77/, seated in one of them, locking the Wheel H, and hence the pattern-chain to rotate with the actuating-Wheel d, and the stud L occupying the position which it assumed immediately after passing over one of the ledges 713. As the key is carried along with the wheel H, the stud L will travel from the abrupt face of one of the ledges it along the plain intervening space It and up the-inclined face of the next succeeding ledge until the key is released from the actuatin g-wheel d. This travel corresponds to the distance between two successive pockets on the actuating-wheel, in the present instance to onesixth of its revolution, and also to the onesixth revolution of the chain -supporting wheel, which brings a new set of rollers or bar of the chain into position to give the desired movement to the vibrator-levers. The completion of the movement of the wheel H, which throws the stud L over the ledge, is acco m plished as hereinbefore described. In this position the pattern-chain will rest untilthe next succeeding pocket in the actuatingwneel D is-brought opposite the head of the keythat is, it will restduring another sixth revolution of the wheel d, and the effect of the set of rollers or bar of the pattern-chain upon the vibrator-levers will be double.

If every alternate pocket inthe actuatingwheel cl be filled by a suitable stopper N, it will follow from the reasons above set forth that the effect of a singleset of rollers or bar on the chain will be three times whatit would be in a continuously-moving chain, since the key will now be held out of engagement with the actuating-wheel through a'distance corresponding to two -sixths or one third of its revolution, Again, if two of the pockets in the wheel d be left open (the two located at equal distances apart) and the remainder of the pockets be filled, it will follow that the effect of a single set of rollers or bar of the chain will be four times what it would be with a constantly-moving chain, while if all the pockets except one be closed its effect will be seven times what it would be if the chain were constantly moving.

Instead of the stop Z, which I have described, I may employ a stop consisting of a roller 0, journaled in a spring-armo and adapted to seat in depressions 0 along the periphery of the wheel H, as shown in Fig. 1.

In the place of the wheel H with ratchetteeth on its periphery and the pawl M, actuated by an eccentric upon the main shaft, I

may employ a polygonal-shaped plate H, (see Fig. 8,) and provide a spring-actuated pawl M, arranged to contact with the periphery of the said plate H, and serving, because of its spring-pressure against the periphery of the plate, to complete its movement and to hold it against forward or backward displacement.

What I claim as my invention is 1. The combination, with a wheel or plate having a movement in unison with the pattern and a pattern-actuating wheel loosely mounted upon a suitable support in proximity to the said wheel or plate and having its axis in line with the axis of said wheel or plate, of a locking and releasing device carried by said Wheel or plate and having a movement relative to the wheel or plate at predetermined intervals to lock the actuatingwheel to the said wheel or plate and release it therefrom, and an operating device with which the locking and releasing device engages during its travel with the wheel or plate, substantially as set forth.

2. The combination, with a Wheel arranged to rotate with the pattern and carrying a spring-actuated key, of a pattern-actuating wheel provided with key-seats at intervals 011 its side for locking it to the key-carrying Wheel and a controlling-plate fixed in position to engage the key and provided with a series of inclines thereon, adapted to release the key from the actuating-wheel at predetermined intervals, substantially as set forth.

3. The combination, with a wheel or plate arranged to rotate with a pattern and carrying a key, of a pattern-actuating Wheel provided with key-seats at intervals thereon, means for releasing the key from the actuating-wheel,

and a device for positively rotating the keycarrying wheel or plate to complete its movement, substantially as set forth.

i. The combination, with a wheel or plate "H, arranged to rotate with the pattern and a pattern-actuating wheel, of a key for locking and releasing the said wheel or plate H to or from its actuating-wheel, means for disengaging the key from the actuatingwheel at predetermined intervals, and a stop for locking the pattern against displacement, substantially as set forth.

5. The combination, with a wheel or plate arranged to rotate with the pattern and carrying a key and an actuating-wheel provided with seats for the key, of a fixed controllingplate provided with a series of inclines in position to engage the key and release it from the actuating-wheel, the main shaft, an eccentric on the main shaft, and a pawl in engagement with the key-carrying wheel and actuated by the said eccentric to complete the movement of the wheel, substantially as set forth.

6. In combination, the pattern-actuating wheel, a key supported to move with the pattern and arranged to lock and release the pattern to and from its actuating mechanism, a controlling-plate having a series of ledges on its side in position to engage the key and a series of notches along its periphery, and a stop carried by the key and adapted to enter the notches and limit the movement of the pattern, substantially as set forth.
